The Beta 58A is a high-output supercardioid dynamic vocal microphone design for professional sound reinforcement and project studio recording. It has become a leading choice among vocalists and touring professionals worldwide.

The Beta 58A maintains a true supercardioid pattern throughout its frequency range. This insures high gain before feback, imum isolation from other sound sources, and minimum off-axis tone coloration. The Beta 58A has a shap frequency response that is ideal for close?up vocals. The superb performance of this microphone is not fect by rough handling because of its r construction, proven shock mount system, and harden steel mesh grille.
